The storage contents are held by the supply of power from the backup power source 300c when the above is not performed. As a result, the main control RAM 100c and the sub control RAM 200c are configured to be able to hold stored contents even after the supply of power is shut off.

Next, in the slot machine 10 of the present embodiment, information on fraud which is stored in the main control RAM 100c will be described together with a specific example.
As shown in FIG. 4, the information regarding the fraud includes save information for temporarily saving (storing and holding) information regarding the process performed by the main control CPU 100 a. Although details will be described later, the save information is information to be rewritten in the second storage area power recovery process executed when the power supply of the slot machine 10 is recovered. The second storage area power recovery process is a process that is executed when the power is recovered, so it can be said that the second storage area power recovery process is a process that may cause fraud. That is, since the save information is information to be rewritten in a process that may cause fraud, it can be said that it is important information regarding fraud. The save information is stored in the storage area of the main control RAM 100 c in the storage area to which the first address determined in advance is allocated in the second storage area. In the following description, the storage area to which each address is assigned is simply referred to as “address storage area”.

The open signal input information is information relating to a state in which the front door 12 is open, which is likely to be tampered with, so it can be said that the open signal input information is important information relating to fraud. The release signal input information is stored in the storage area of the second control area in the second storage area among the storage areas of the main control RAM 100c. Further, since the door open flag is a flag indicating that the front door 12 is open, it is a state that fraud is likely to be performed, and thus it can be said that it is important information regarding fraud. The door open flag is stored in a storage area of a third address predetermined in the second storage area among the storage areas of the main control RAM 100c.

  Further, in the information on fraud in this embodiment, operation signal input information indicating whether or not an operation signal indicating that the setting device 26 is operated is input, or that the setting device 26 is operated. There is a setter operation flag to indicate. The operation signal input information is information relating to the setting unit 26 which is easily tampered with because the operation of changing the payout rate directly linked to the player's profit is possible, and thus it can be said to be important information regarding fraud. The operation signal input information is stored in the storage area of the second control area in the second storage area among the storage areas of the main control RAM 100c. The operation signal input information is stored in another bit in the storage area of the second address which is the same as the open signal input signal described above. Further, since the setter operation flag is a flag related to the setter 26 that is easily tampered with because the operation to change the payout rate directly linked to the player's profit is possible, it is considered to be important information regarding fraud. It can be said. The setter operation flag is stored in the storage area of the second storage area in the storage area of the main control RAM 100 c in the storage area of the fourth address determined in advance.

  As described above, in the present embodiment, at least a part of the information regarding the fraud is stored in the second storage area of the main control RAM 100c. In other words, important information regarding fraud is stored in the second storage area.

  In the present embodiment, the first to fourth addresses may be different addresses among the addresses “F200H to F3FFH” of the second storage area, or may be the same address. When one storage area is shared by a plurality of pieces of information by setting the first to fourth addresses as the same address, it is preferable to rewrite each bit associated with each piece of information. Further, in the present specification, the first to fourth numbers of the first to fourth addresses are given for the convenience of description, and the order of the addresses in the storage area of the main control RAM 100c is specified. It is not something to do. For example, among the addresses "F200H to F3FFH" of the second storage area, the first to fourth addresses are four consecutive addresses in ascending order in the order of the first address → second address → ... → fourth address. It may be an address other than this.

  Hereinafter, various processes executed by the main control CPU 100a based on the main control program will be described. First, the game progress processing regarding the progress of the game will be described. In the present embodiment, the game progress processing corresponds to a main routine.

  As shown in FIG. 5, in the game progression process, the main control CPU 100a performs a game start set process (step Sa01). In the game start setting process, the main control CPU 100a stores information such as the gaming state of the slot machine 10 and a flag related to effects (so-called freeze effects) using the reel unit 16 in the first storage area of the main control RAM 100c. And a process of initializing a predetermined storage area in the first storage area. In the present embodiment, the main control CPU 100a can independently execute the process of initializing the first storage area of the main control RAM 100c and the process of initializing the second storage area. In other words, the first storage area and the second storage area can be independently initialized.

  Next, the main control CPU 100a starts accepting medal bets (step Sa02). Next, the main control CPU 100a checks the gaming state of the slot machine 10 (step Sa03). At step Sa03, the main control CPU 100a specifies whether or not the gaming state of the slot machine 10 is a bonus game.

  Next, the main control CPU 100a determines whether or not it is at the time of replay operation (step Sa04). When it is not during replay operation (step Sa04: NO), the main control CPU 100a performs medal management processing for setting the number of bets in the current variation game (step Sa05). In the process of step Sa05, when the detection signal of the medal is inputted from the insertion sensor, the main control CPU 100a adds 1 to the bet number stored in the first storage area of the main control RAM 100c. When the main control CPU 100a inputs an operation signal from the bet button 18 in the process of step Sa05, the main control CPU 100a adds the bet number stored in the main control RAM 100c to the bet number so that the bet number becomes the prescribed bet number. The credits stored in the first storage area of the main control RAM 100c are subtracted by the added amount.

  When it is at the time of replay operation (step Sa04: YES), or when the process of step Sa05 is ended, the main control CPU 100a determines whether or not the bet number in the current variation game matches the maximum bet number. (Step Sa06). In addition, when it is at the time of replay operation (step Sa04: YES), the main control CPU 100a resets the bet number in the previous fluctuation game as the bet number in the current fluctuation game.

  If the bet number in the current variation game does not match the maximum bet number (step Sa06: NO), the main control CPU 100a proceeds to the process of step Sa03. That is, in the process of step Sa06, the main control CPU 100a determines whether or not the variation game can be started. On the other hand, when the bet number in the current variation game matches the maximum bet number (step Sa06: YES), the main control CPU 100a determines whether a start operation by the start lever 20 has been received (step Sa07). In the process of step Sa07, the main control CPU 100a makes an affirmative determination when an operation signal is input from the start lever 20, and a negative determination when no operation signal is input from the start lever 20. If the start operation has not been received (step Sa07: NO), the main control CPU 100a proceeds to the process of step Sa03.

  On the other hand, when the start operation has been received (step Sa07: YES), the main control CPU 100a determines the winning information (step Sa08). At step Sa08, the main control CPU 100a determines one piece of winning information by lottery using the value of the random number for winning information determination. The process of step Sa08 is a combination lottery (internal lottery) internally performed in the slot machine 10. Further, the main control CPU 100a instructs the start of the change game in the process of step Sa08, and generates a change game start command capable of specifying the determined winning information (symbol combination (combination)), Control to output. In the present embodiment, the role lottery in the process of step Sa08 corresponds to a lottery as to whether or not to give a profit. That is, the game progress processing includes processing relating to a lottery on whether to give a profit or not.

  Next, the main control CPU 100a determines whether or not the shortest game time (wait time) has elapsed (step Sa09). When the shortest game time has not elapsed (step Sa09: NO), the main control CPU 100a stands by until the shortest game time elapses. When the shortest game time has elapsed (step Sa09: YES), the main control CPU 100a outputs an operation signal (drive signal) to the actuators A1 to A3 to start the rotation of each of the reels 16a to 16c, and the fluctuation game Start (step Sa10).

  Subsequently, the main control CPU 100a determines whether a stop operation has been received by any of the stop buttons 21a to 21c (step Sa11). In step Sa11, when the main control CPU 100a inputs an operation signal from any of the stop buttons 21a to 21c, the main control CPU 100a makes an affirmative determination, while it does not input an operation signal from any of the stop buttons 21a to 21c. Decide negative.

  When the stop operation has been received (step Sa11: YES), the main control CPU 100a determines a symbol to be displayed on the pay line for stop display based on the determined winning information and the operation timing of the stop button, and the determination is made. The symbol combination control is executed to stop and display the selected symbol on the pay line (step Sa12).

  When the stop operation has not been received (step Sa11: NO), and when the process of step Sa12 is ended, the main control CPU 100a determines whether all the reels 16a to 16c have been stopped (step Sa13) . When one or more reels among the reels 16a to 16c are not stopped (step Sa13: NO), the main control CPU 100a proceeds to the process of step Sa11.

  On the other hand, when all the reels 16a to 16c are stopped (step Sa13: YES), the main control CPU 100a executes display symbol determination (step Sa14). In the process of step Sa14, the main control CPU 100a determines whether or not the symbol combination stopped and displayed on the effective line NL in each reel is any symbol combination (combination) that determines an award, and the award If the symbol combination is determined, the symbol combination is determined. That is, in the process of step Sa14, the main control CPU 100a has won the prize combination whether or not it has actually won a symbol combination (combination) that can be identified from the winning information determined in the process of step Sa08. The symbol combination is determined.

  Next, the main control CPU 100a determines whether to pay out the medals to the player (step Sa15). In step Sa15, the main control CPU 100a makes an affirmative determination if it is a winning combination, while it makes a negative determination if it is not a winning combination. When the medal is dispensed (step Sa15: YES), the main control CPU 100a drives the hopper unit to execute medal payout processing for paying out the medal (step Sa16). Thus, in the slot machine 10, medals can be paid out according to the symbol combination stopped and displayed on the activated line NL.

  When the payout of medals is not performed (step Sa15: NO) and the process of step Sa16 is ended, the main control CPU 100a performs an end process of ending one variation game (step Sa17). That is, in the slot machine 10 of the present embodiment, the game can be ended by the symbol combination being derived and displayed. In the ending process of step Sa17, the main control CPU 100a outputs, to the sub-substrate 200, control to shift the internal state according to the symbol combination (combination) determined to be winning, and a winning instruction command indicating that it is determined to be winning. Take control. The winning instruction command causes the sub-substrate 200 to recognize the winning of the symbol combination (combination) indicated by the variation game start command. After that, the main control CPU 100a ends the game progress processing related to the execution of one fluctuation game, and shifts to the processing of step Sa01 again.

  As described above, the main control CPU 100a relates to the progress of the game, for example, the winning information determined in the process of step Sa08, the gaming state of the slot machine 10, and a flag related to effects using the reel unit 16 in the game proceeding process. The storage content of the first storage area is rewritten according to the processing result, such as storing information in the first storage area. On the other hand, the main control CPU 100a does not rewrite the storage content of the second storage area in principle in the game progression processing. In other words, the game progress processing of the present embodiment rewrites the storage content of the first storage area in the storage area of the main control RAM 100c according to the processing result, except for a part of the processing into a subroutine described later. On the other hand, it is a process which does not rewrite the storage content of the second storage area.

  Here, in the present specification, when simply “do not rewrite the storage content of a specific storage area in a specific process”, of the processes included in the “specific process”, the “specific process” is being executed. It is intended not to rewrite the storage content of the “specific storage area” along with the execution of the processing excluding the processing (subroutine) called to That is, even in the present specification, even when it is indicated that "the storage content of the specific storage area is not rewritten in the specific processing", the "specific storage area" in the process called during the execution of the "specific process" There are times when the memory contents of are rewritten. Further, in the present specification, when simply “rewrite the storage content of a specific storage area in a specific process” is called out during the execution of the “specific process” among the processes included in the “specific process”. With the execution of the processing excluding the processing (subroutine) to be performed, it is intended to rewrite the storage content of the “specific storage area”.

  Next, power-off processing performed when the main control CPU 100a receives a power-off signal will be described. That is, the power-off process is a process performed when the power of the slot machine 10 is shut off.

  As shown in FIG. 6, in the power-off process, the main control CPU 100a saves a predetermined register (step Sb01). In the process of step Sb01, the main control CPU 100a stores the storage content of the predetermined register in the first storage area of the main control RAM 100c.

  Subsequently, the main control CPU 100a stores the interruption state at the time of power-off in the first storage area of the main control RAM 100c (step Sb02). Here, the interrupt state is a state as to whether execution of interrupt processing is permitted. The interrupt process of the present embodiment is executed at predetermined intervals when execution of the interrupt process is permitted. In the following description, to permit the execution of the interrupt process is simply referred to as "permit interrupt", and not to allow the execution of the interrupt process is simply referred to as "prohibit interrupt".

  In the process of step Sb02, the main control CPU 100a stores the interrupt state information capable of specifying whether or not the interrupt is permitted when the power-off signal is input, and then stores the predetermined register. Are stored in the first storage area of the main control RAM 100c.

  Thereafter, the main control CPU 100a saves the registers other than the predetermined register (step Sb03). In the process of step Sb03, the main control CPU 100a stores the storage contents of registers other than the predetermined register in the first storage area of the main control RAM 100c. Then, in the first storage area, the main control CPU 100a specifies, in the first storage area of the main control RAM 100c, a stack pointer capable of specifying an address of a stack area for storing information (control information) according to the processing result next. It memorizes (step Sb04).

  After that, the main control CPU 100a sets a power-off process completed flag in the first storage area of the main control RAM 100c (step Sb05). When the processing of step Sb01 to step Sb04 is normally performed in step Sb05, the main control CPU 100a sets a flag capable of identifying that the processing is normally performed, while the process of step Sb01 to step Sb04 is performed. If the normal operation is not performed, a flag is set that can identify that the normal operation was not performed.

  Then, the main control CPU 100a erases the checksum data stored in the first storage area of the main control RAM 100c (step Sb06). Thereafter, the main control CPU 100a calculates a checksum of the main control RAM 100c (step Sb07). In the process of step Sb07, the main control CPU 100a calculates a checksum for all storage areas (all address ranges) of the main control RAM 100c. That is, in the process of step Sb07, the main control CPU 100a calculates a checksum with reference to both the storage content of the first storage area of the main control RAM 100c and the storage content of the second storage area.

  Subsequently, the main control CPU 100a stores the checksum value calculated in step Sb07 as checksum data in the first storage area of the main control RAM 100c (step Sb08). Thereafter, the main control CPU 100a prohibits access to the main control RAM 100c (step Sb09). Thereafter, the main control CPU 100a waits until the supply of power is started.

  As described above, the main control CPU 100a rewrites the storage content of the first storage area according to the processing result in the power-off process. On the other hand, the main control CPU 100a does not rewrite the storage content of the second storage area in the power-off process. In other words, the power-off process of the present embodiment is a process in which the storage contents of the first storage area among the storage areas of the main control RAM 100c are rewritten according to the processing result, while the storage contents of the second storage area are not rewritten. It is. Further, the main control CPU 100a can refer to both the storage content of the first storage area of the main control RAM 100c and the storage content of the second storage area in the power-off process.

  Next, the power on process performed by the main control CPU 100a when the supply of power to the slot machine 10 is started will be described. That is, the power on process is a process performed when the slot machine 10 is powered on. In the present embodiment, the power-on process corresponds to the start process and the first start process.

  As shown in FIG. 7, in the power-on process, the main control CPU 100a sets a stack pointer that can specify the address of the stack area of the first storage area (step Sc01). Subsequently, the main control CPU 100a executes initial setting of the main control CPU 100a (step Sc02).

  Thereafter, the main control CPU 100a performs a second storage area power on process including the determination of whether the front door 12 is opened and the determination of whether the setter 26 is operated (step Sc03). Details of the second storage area power on process will be described later.

  Subsequently, the main control CPU 100a refers to the storage area of the third address in the second storage area of the main control RAM 100c, and determines whether the door open flag is set (with the door open flag) or not. It determines (step Sc04). If the door open flag is not set (step Sc04: NO), the main control CPU 100a shifts to a power recovery process for recovering the state of the slot machine 10 at the time of power shutdown. Details of the power supply recovery process will be described later.

  On the other hand, when the door open flag is set (step Sc04: YES), the main control CPU 100a refers to the storage area of the fourth address in the second storage area of the main control RAM 100c to operate the setter It is determined whether the flag is set (setting device operation flag is present) (step Sc05). When the setter operation flag is not set (step Sc05: NO), the main control CPU 100a shifts to the power supply recovery process.

  On the other hand, when the setter operation flag is set (step Sc05: YES), the main control CPU 100a can specify the setting of the slot machine 10 stored in the first storage area of the main control RAM 100c. It is determined whether or not the setting of the slot machine 10 is normal with reference to (setting value) (step Sc06). Here, in the determination of whether the setting of the slot machine 10 is normal or not, whether the setting step that can be specified from the setting information is within the setting step range prepared in the slot machine 10 in advance. It can be judged by whether it is not.

  If the setting of the slot machine 10 is not normal (step Sc06: NO), the main control CPU 100a sets a predetermined setting as the setting of the slot machine 10 (step Sc07). Specifically, in the present embodiment, setting information capable of specifying a setting that is not most advantageous to the player is stored in the first storage area of the main control RAM 100c.

  When the setting of the slot machine 10 is normal (step Sc06: YES), and when the process of step Sc07 ends, the main control CPU 100a refers to the storage content of the first storage area of the main control RAM 100c, It is determined whether the storage content of the one storage area is normal (step Sc08). That is, the power-on process of the present embodiment is a process including checking whether or not the storage content of the first storage area is normal. If the storage content of the first storage area is not normal (step Sc08: NO), the main control CPU 100a causes an error stop. Here, to cause an error stop is to stop various processes since an unrecoverable error state has occurred.

  On the other hand, when the storage content of the first storage area is normal (step Sc08: YES), the main control CPU 100a initializes a predetermined storage area in the first storage area of the main control RAM 100c (step Sc09) . That is, the power-on process of the present embodiment is a process including initializing the storage content of the first storage area. Here, in the present specification, “initialization” is to rewrite the storage area to be initialized into predetermined information (initial information). That is, initialization is a process corresponding to rewriting of stored contents. In the process of step Sc09, the main control CPU 100a does not initialize at least the storage area in which the setting information is stored in the first storage area. Thereby, it is possible to suppress the occurrence of a situation where the change of the setting due to the operation is not reflected although the setting device 26 is operated.

  Thereafter, the main control CPU 100a checks whether or not the storage content of the second storage area of the main control RAM 100c is normal, and performs a second storage area check initialization process for initialization (step Sc10). . Details of the second storage area check initialization process will be described later.

  Subsequently, the main control CPU 100a permits an interrupt (step Sc11). Then, the main control CPU 100a performs setting change processing for changing the setting of the slot machine 10 (step Sc12).

  In the setting change process, the main control CPU 100a changes the setting that can be set as the setting of the slot machine 10 by one step each time the predetermined change operation means is operated. Here, the predetermined change operation means may be an operation means dedicated to setting change, or may be an operation means shared with other operation means such as the bet button 18, for example. Then, when the predetermined determination operation means (for example, the start lever 20 or the like) is operated, the main control CPU 100a sets the setting selected when the determination operation means is operated with the setting of the slot machine 10 Decide to do. Thereafter, when the operation of the setting device 26 is completed, the main control CPU 100a stores setting information capable of specifying the determined setting of the slot machine 10 in the first storage area of the main control RAM 100c, and ends the setting change processing. Do. When the setting change process ends, the main control CPU 100a ends the power-on process.

  As described above, the main control CPU 100a rewrites the storage content of the first storage area according to the processing result in the power-on process. On the other hand, the main control CPU 100a does not rewrite the storage content of the second storage area in the power-on process. In other words, the power-on process of the present embodiment is a process that does not rewrite the storage content of the second storage area while rewriting the storage content of the first storage area among the storage areas of the main control RAM 100c according to the processing result. It is. Further, the main control CPU 100a can refer to both the storage content of the first storage area of the main control RAM 100c and the storage content of the second storage area in the power-on process.

  Next, the second storage area power-on process will be described. The second storage area power-on process is performed in step Sc03 of the power-on process, and thus can be grasped as a process (so-called, subroutine) called in the power-on process.

  As shown in FIG. 8, in the second storage area power-on process, the main control CPU 100 a determines whether the front door 12 is opened (step Sd 01). In the process of step Sd01, the main control CPU 100a refers to the release signal input information stored in the storage area of the second address in the second storage area of the main control RAM 100c, and the front door 12 is opened. It is specified whether or not an open signal indicating that is being input is input. Then, the main control CPU 100a determines that the front door 12 is open when the open signal is input, and the front door 12 is open when the open signal is not input. It is determined that there is not. If it is determined that the front door 12 is opened (step Sd01: YES), the main control CPU 100a sets a door open flag in the storage area of the third address in the second storage area of the main control RAM 100c. (Step Sd02).

  When it is determined that the front door 12 is not opened (step Sd01: NO), and when the process of step Sd02 is ended, the main control CPU 100a determines whether the setting device 26 is operated (step Sd03). In the process of step Sd03, the main control CPU 100a operates the setter 26 with reference to the operation signal input information stored in the storage area of the second address in the second storage area of the main control RAM 100c. It is specified whether or not an operation signal indicating that is being input is input. Then, the main control CPU 100a determines that the setter 26 is being operated when the operation signal is input, while the setter 26 is operated when the operation signal is not input. It is determined that there is not. When it is determined that the setting device 26 is operated (step Sd03: YES), the main control CPU 100a sets the setting device operation flag in the storage area of the fourth address in the second storage area of the main control RAM 100c. To do (step Sd04).

  If it is determined that the setting device 26 has not been operated (step Sd03: NO), and if the process of step Sd04 is ended, the main control CPU 100a ends the second storage area power on process.

  As described above, the main control CPU 100a rewrites the storage content of the second storage area according to the processing result in the second storage area power-on process. On the other hand, the main control CPU 100a does not rewrite the storage content of the first storage area in the second storage area power-on process. In other words, while the second storage area power-on process of the present embodiment rewrites the storage contents of the second storage area among the storage areas of the main control RAM 100c according to the processing result, the storage contents of the first storage area Is a process that does not rewrite

  The second storage area power-on process of the present embodiment is a process including determining whether or not the front door 12 is opened, and thus can be grasped as a process related to the open state of the front door 12. That is, the second storage area power on process corresponds to the open state process. Further, since the second storage area power-on process of the present embodiment is a process including determining whether the setter 26 is operated, it can be grasped as a process related to the operation state of the setter 26. That is, the second storage area power on processing corresponds to the operation state processing.

  Next, the second storage area check initialization process will be described. Since the second storage area check initialization process is executed in step Sc10 of the power on process, it can be grasped as a process (so-called, subroutine) called in the power on process. In the present embodiment, the second storage area check initialization process corresponds to a second start process.

  As shown in FIG. 9, in the second storage area check initialization process, the main control CPU 100a refers to the storage contents of the second storage area of the main control RAM 100c, and the storage contents of the second storage area are normal. It is determined whether or not it is (step Se01). That is, the second storage area check initialization process of the present embodiment is a process including checking whether or not the storage content of the second storage area is normal. If the storage content of the second storage area is not normal (step Se01: NO), the main control CPU 100a causes an error stop.

  On the other hand, when the storage content of the second storage area is normal (step Se01: YES), the main control CPU 100a initializes a predetermined storage area of the second storage area (step Se02). That is, the second storage area check initialization process of the present embodiment is a process including initializing the storage content of the second storage area. Thereafter, the main control CPU 100a ends the second storage area check initialization process.

  As described above, in the second storage area check initialization process, the main control CPU 100a rewrites the storage content of the second storage area according to the processing result. On the other hand, the main control CPU 100a does not rewrite the storage content of the first storage area in the second storage area check initialization process. In other words, the second storage area check initialization process of the present embodiment rewrites the storage contents of the second storage area among the storage areas of the main control RAM 100c according to the processing result, while storing the first storage area. It is a process that does not rewrite the content.

Next, the power supply recovery process will be described. In the present embodiment, the power recovery process corresponds to a first process and a first power failure recovery process.
As shown in FIG. 10, in the power supply recovery process, the main control CPU 100a calculates a check sum of the main control RAM 100c (step Sf01). In the process of step Sf01, the main control CPU 100a calculates a checksum for all storage areas of the main control RAM 100c as in the process of step Sb07 in the power-off process.

  Subsequently, the main control CPU 100a determines whether the calculated checksum is normal (step Sf02). In step Sf02, the main control CPU 100a compares the checksum calculated in step Sf01 with the checksum stored in the first storage area of the main control RAM 100c in the processing of step Sb08 in the power-off process, If they match, it is determined that they are normal, but if they are not match, they are determined that they are not normal. If the checksum is not normal (step Sf02: NO), the main control CPU 100a causes an error stop.

  On the other hand, when the checksum is normal (step Sf02: YES), the main control CPU 100a restores the stack pointer (step Sf03). Subsequently, the main control CPU 100a executes a second storage area power recovery process for determining whether or not the power-off process has been normally performed (step Sf04). Details of the second storage area power recovery process will be described later.

  Thereafter, the main control CPU 100a initializes a storage area excluding the maximum use area of the work area and the stack area in the first storage area of the main control RAM 100c (step Sf05). Subsequently, the main control CPU 100a restores the registers other than the predetermined register (step Sf06).

  After that, the main control CPU 100a refers to the interrupt state when the power is turned off (when the supplied voltage becomes lower than a predetermined voltage), and determines whether the interrupt is permitted (step Sf07). In the process of step Sf07, the main control CPU 100a refers to the interrupt state information stored in the first storage area of the main control RAM 100c in step Sb02 of the power-off process, and determines whether the interrupt is permitted or not. judge.

  When the interrupt is permitted when the power is turned off (step Sf07: YES), the main control CPU 100a restores a predetermined register (step Sf08). Thereafter, the main control CPU 100a permits an interrupt (step Sf09). Then, the main control CPU 100a ends the power return processing, and returns to the game progress processing when the power is turned off. In this way, it is possible to return to the state where it is possible to play a game while the interruption is permitted.

  On the other hand, when the interrupt is not permitted (disallowed) at the time of power-off (step Sf07: NO), the main control CPU 100a restores the predetermined register as in step Sf08 (step Sf10). Then, the main control CPU 100a ends the power return processing, and returns to the game progress processing when the power is turned off. As a result, it is possible to return to the state where it is possible to play a game without interruption being permitted.

  As described above, the main control CPU 100a rewrites the storage content of the first storage area according to the processing result in the power recovery process. On the other hand, the main control CPU 100a does not rewrite the storage content of the second storage area in the power recovery process. In other words, in the power recovery process of the present embodiment, the storage contents of the first storage area among the storage areas of the main control RAM 100c are rewritten according to the processing result, while the storage contents of the second storage area are not rewritten. It is. Further, the main control CPU 100a can refer to both the storage content of the first storage area of the main control RAM 100c and the storage content of the second storage area in the power recovery process.

  Next, the second storage area power recovery process will be described. Since the second storage area power recovery process is executed in step Sf04 of the power recovery process, it can be grasped as a process (so-called, subroutine) called in the power recovery process. In the present embodiment, the second storage area power recovery process corresponds to a second process and a second power failure recovery process.

  As shown in FIG. 11, in the second storage area power recovery process, the main control CPU 100a refers to the stack pointer of the first storage area of the main control RAM 100c, and saves save information that can specify the stack pointer. 2. Store (save) in the storage area of the first address of the two storage areas (step Sg01). Subsequently, the main control CPU 100a saves all the registers in the stack area of the second storage area (step Sg02).

  After that, the main control CPU 100a refers to the storage contents of the first storage area of the main control RAM 100c, and determines whether the power-off process completion flag is set (with the power-off process completion flag) (step Sg03). If the power-off process completion flag is set (step Sg03: YES), the main control CPU 100a refers to the storage content of the first storage area of the main control RAM 100c, and determines whether the stack pointer is normal or not. It determines (step Sg04). Whether or not the stack pointer is normal can be determined by whether or not the value indicated by the stack pointer is within the address range (within the numerical range) defined as the stack area. The process of step Sg04 can also be performed with reference to the save information stored in the storage area of the first address in the second storage area. If the stack pointer is normal (step Sg04: YES), the main control CPU 100a refers to the storage content of the first storage area of the main control RAM 100c and determines whether or not the setting of the slot machine 10 is normal. To do (step Sg05).

  If the setting of the slot machine 10 is normal (step Sg05: YES), the main control CPU 100a restores all the registers from the stack area of the second storage area (step Sg06). Subsequently, the main control CPU 100a refers to the storage area of the first address in the second storage area, and restores the stack pointer of the first storage area that has been saved (step Sg07). The process of step Sg07 specifies the process to be restored after the second storage area power recovery process based on the stack pointer of the first storage area that can be identified from the save information stored (saved) in the process of step Sg01. It does not rewrite the storage content of the first storage area. After that, the main control CPU 100a ends the second storage area power recovery process.

  On the other hand, when the power-off process completion flag is not set (step Sg03: NO), the stack pointer is not normal (step Sg04: NO), and the setting of the slot machine 10 is not normal (step Sg05: NO). The main control CPU 100a causes an error stop. In the present embodiment, when the power-off process completion flag is not set or when the stack pointer is not normal or when the setting of the slot machine 10 is not normal, for example, the storage content of the main control RAM 100c is incorrect. If it is rewritten to Therefore, the second storage area power recovery process of the present embodiment can be grasped as a process relating to the fraud of the slot machine 10.

  As described above, the main control CPU 100a rewrites the storage content of the second storage area according to the processing result in the second storage area power recovery process. On the other hand, the main control CPU 100a does not rewrite the storage content of the first storage area in the second storage area power recovery process. In other words, the second storage area power recovery process of the present embodiment rewrites the storage contents of the second storage area among the storage areas of the main control RAM 100c according to the processing result, while the storage contents of the first storage area Is a process that does not rewrite Further, the main control CPU 100a can refer to both the storage content of the first storage area of the main control RAM 100c and the storage content of the second storage area in the second storage area power recovery process.

Next, the operation of the slot machine 10 configured as described above will be described.
As shown in FIG. 12, the processes that can be executed by the main control CPU 100a of the present embodiment are a first type of process in which the first storage area is to be rewritten and a second type of process in which the second storage area is to be rewritten. And can be classified. In the present embodiment, the first type processing corresponds to the first processing, and the second type processing corresponds to the second processing.

  In the first type processing of the present embodiment, gaming progress processing, power off processing, power on processing, and power recovery processing are classified. Further, the second storage area power on process, the second storage area check initialization process, and the second storage area power recovery process are classified into the second type process of the present embodiment. As described above, the second type processing is all processing relating to fraud.

  The main control CPU 100a of the present embodiment rewrites the storage content of the second storage area of the main control RAM 100c in the processing of rewriting the storage content of the first storage area of the main control RAM 100c, such as the first type processing. Absent. Further, the main control CPU 100a does not rewrite the storage content of the first storage area of the main control RAM 100c in the processing of rewriting the storage content of the second storage area of the main control RAM 100c, such as the second type processing. That is, the main control CPU 100a according to the present embodiment varies the storage area for rewriting the storage content according to the process to be executed.

  In other words, the first storage area can be grasped as a usable (rewritable) use area for the first type processing, while it can not be used (nonrewritable) non-use area for the second type processing It can be grasped as used area). Further, the second storage area can be regarded as an unusable (non-rewritable) non-use area (unused area) for the first type processing, but usable (rewritable) for the second type processing It can be understood as an area. That is, while the first type processing is processing in which the address for storing information indicating the processing result is in the first storage area, the second type processing is storing the information indicating the processing result in the second storage area Is a process that

  Further, the main control CPU 100a according to the present embodiment performs both of the storage contents of the first storage area and the storage contents of the second storage area in the power-off process, the power-on process, and the power recovery process among the first-type processes. I can refer to it. That is, in the process of rewriting the storage contents of the first storage area, the main control CPU 100a uses the storage contents of the first storage area based on both the storage contents of the first storage area and the storage contents of the second storage area. It can be rewritten. Further, the main control CPU 100a can refer to both the storage content of the first storage area and the storage content of the second storage area in the second storage area power recovery process among the second type processing. That is, in the process of rewriting the storage contents of the second storage area, the main control CPU 100a uses the storage contents of the second storage area based on both the storage contents of the first storage area and the storage contents of the second storage area. It can be rewritten.

  The main control CPU 100a according to the present embodiment also performs save information capable of specifying the stack pointer of the first storage area and the storage contents of all the registers in the second storage area power recovery process among the second type processing. Store (save) in the second storage area. Then, the main control CPU 100a refers to the stored contents and restores the stack pointer and all the registers. For this reason, the main control CPU 100a can suppress that the storage contents of the stack pointer of the first storage area and all the registers are rewritten due to illegalness or the like during execution of the process of rewriting the storage area of the second storage area.

  Further, the main control CPU 100a of the present embodiment is configured to be able to call and execute another type 1 processing or type 2 processing in the type 1 processing. On the other hand, the main control CPU 100a can not call up and execute another type 2 process or type 1 process in the type 2 process.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) With regard to various processes performed by the main control CPU 100a, since the storage area to be rewritten can be made different among the storage areas of the main control RAM 100c for each process, the various processes correspond to the storage areas to be rewritten The management of the storage area of the main control RAM 100c can be facilitated.

  (2) In particular, in the power recovery processing which is the first type processing, while rewriting the storage contents of the first storage area, the storage contents of the second storage area are not rewritten. Further, in the second storage area power recovery process, which is a second type process called in the power recovery process, the storage contents of the second storage area are rewritten while the storage contents of the first storage area are not rewritten. Thus, management of the storage area of the main control RAM 100c can be further facilitated by associating the storage areas to be rewritten between the first type processing and the second type processing called by the first type processing.

  (3) In the first type processing such as power on processing and power recovery processing, since the storage contents of the second storage area to be rewritten in the second type processing can be referred to, the same processing as the second type processing There is no need to perform processing, and processing of the gaming machine can be made more efficient overall.

  (4) For example, in the power recovery process, since the storage contents of the second storage area to be rewritten in the second storage area power recovery process can be referred to, the same process as the second storage area power recovery process is performed in the power recovery process There is no need for this, and the processing of the gaming machine can be made generally efficient.

  (5) Further, in the power on process, since the storage contents of the second storage area to be rewritten in the second storage area check initialization process can be referred to, the same process as the second storage area check initialization process is powered on It is not necessary to carry out the processing of the game machine, and the processing of the gaming machine can be made generally efficient.

  (6) Further, in the power-on process, since the storage contents of the second storage area to be rewritten in the second storage area power-on process can be referred to, the same process as the second storage area power-on process is performed by the power-on process There is no need for this, and the processing of the gaming machine can be made generally efficient.

  (7) Specifically, in the second storage area power-on process, it is determined whether or not the front door 12 is opened, and a door open flag is set in the second storage area. Then, in the power-on process, the door open flag of the second storage area set in the second storage area power-on process can be referred to, so it is not necessary to perform the process as to whether the front door 12 is opened. Therefore, the processing content of the power-on processing can be streamlined.

  (8) Further, in the second storage area power on process, it is determined whether or not the setter 26 is operated, and the setter operation flag is set in the second storage area. Then, in the power-on process, since the setter operation flag of the second storage area set in the second storage area power-on process can be referred to, it is not necessary to perform the process of whether the setter 26 is operated. Therefore, the processing content of the power-on processing can be streamlined.

  (9) In the second type processing such as the second storage area power recovery processing, since the storage contents of the first storage area to be rewritten in the first type processing can be referred to, the same processing as the first type processing There is no need to perform seed processing, and processing of the gaming machine can be made more efficient overall.

  (10) For example, in the second storage area power recovery process, since the storage contents of the first storage area to be rewritten in the power recovery process can be referred to, the same processing as the power recovery process is performed in the second storage area power recovery process There is no need for this, and the processing of the gaming machine can be made generally efficient.

  (11) The power recovery process and the second storage area power recovery process are processes performed at the time of power recovery of the slot machine 10. Therefore, it can be said that they are important processes that are easily fraudulent. In the present embodiment, since the storage areas to be rewritten are made different from each other for the power recovery process and the second storage area power recovery process, which are such important processes, mixing of unnecessary storage contents is suppressed, Security can be improved.

  (12) Second storage area In the power supply recovery process, save information capable of specifying the stack pointer of the first storage area and the storage contents of all the registers are saved in the second storage area. It is possible to prevent the stored contents of the stack pointer and all the registers from being rewritten. Therefore, the mixing of unnecessary memory contents can be suppressed, and the security can be further improved.

  (13) In the second storage area power recovery process, which is processing relating to the fraud of the slot machine 10, the storage content of the second storage area is rewritten. In other words, in the second storage area, information on fraud is stored. According to this, since the content stored in each storage area can be made regular, management of the storage area of the main control RAM 100c can be further facilitated.

  (14) Since the power on process and the second storage area check initialization process are processes performed when the slot machine 10 is powered on, it can be said that it is an important process in which fraud is easily performed. In the present embodiment, since the storage areas to be rewritten are made different from each other in the power-on process and the second storage area check initialization process, which are such important processes, mixing of unnecessary storage contents is suppressed. , Can improve security.

  (15) The power-on process includes initializing the storage content of the first storage area, and the second storage area check initialization process includes initializing the storage content of the second storage area. Thus, each process can be associated with the storage area to be the target of initialization of the storage content, and the management of the storage area of the main control RAM 100c can be further facilitated.

  (16) The power-on process includes checking whether the storage content of the first storage area is normal, and the initialization processing of the second storage area check is that the storage content of the second storage area is normal Including checking whether or not. As a result, each process can be associated with the storage area to be checked for the storage content, and management of the storage area of the main control RAM 100c can be further facilitated.

  (17) Since the second storage area power-on process is a process including determining whether or not the front door 12 is opened, it is considered that the important process related to fraud performed by opening the front door 12 It can be said. In the present embodiment, the second storage area power-on process, which is an important process, is performed as a subroutine of the power-on process, and the first storage area is not the first storage area to be rewritten in the power-on process. The storage content of the second storage area different from the storage area is rewritten. Therefore, management of the storage area of the main control RAM 100c can be further facilitated, and mixing of unnecessary storage contents can be suppressed, and security can be improved.

  (18) Further, since the second storage area power-on process is a process including determining whether the setting device 26 capable of changing the setting of the slot machine 10 is operated, fraud is easily performed It can be said that this is an important process related to the setting device 26. In the present embodiment, the second storage area power-on process, which is an important process, is performed as a subroutine of the power-on process, and the first storage area is not the first storage area to be rewritten in the power-on process. The storage content of the second storage area different from the storage area is rewritten. Therefore, management of the storage area of the main control RAM 100c can be further facilitated, and mixing of unnecessary storage contents can be suppressed, and security can be improved.

The above embodiment may be modified as follows.
In the storage area of the main control RAM 100c, how to define the first storage area and the second storage area may be changed as appropriate. For example, the second storage area may be a storage area allocated to an address before the first storage area. Moreover, in each storage area, an unused area may not be set. That is, the storage area to be rewritten and the storage area not to be rewritten may be different depending on the type of processing performed by the main control CPU 100a.

  The first storage area and the second storage area do not have to be storage areas in the same RAM provided on the same substrate, for example, are storage areas in another RAM provided on the same substrate It may be a storage area in another RAM provided on another substrate. In this case, both of the plurality of RAMs correspond to the storage unit.

  The storage contents to be stored in the first storage area and the storage contents to be stored in the second storage area may be changed as appropriate. For example, information on fraud may be stored in the first storage area, or information on the progress of a game may be stored in the second storage area. However, from the viewpoint of facilitating the management of the storage area of the main control RAM 100c, it is preferable to classify the information according to the type and to vary the storage area to be stored according to the type of the information. The types of information include information on control of reels, information on effects, and the like, in addition to the information on the progress of the game and the information on fraud as described in the above embodiment.

  The main control CPU 100a not only rewrites the storage content of the first storage area of the main control RAM 100c nor the storage content of the second storage area in addition to the first type processing and the second type processing. You may go. Further, in such third type processing, both of the storage content of the first storage area and the storage content of the second storage area may be referred to. In this case, in the third type processing, since both of the storage content of the first storage area and the storage content of the second storage area can be referred to, while the management of the storage unit is facilitated, the entire processing of the gaming machine is further performed. It can be efficient. Further, the main control CPU 100a may refer to only one of the storage content of the first storage area and the storage content of the second storage area in the third type of processing, or may not refer to either of them. It is also good. As the third type of processing, for example, the storage content of at least one of the storage content of the first storage area and the storage content of the second storage area is referred to, and a different subroutine is called and executed based on the referenced result. Processing etc. can be assumed. Further, as the third type processing, for example, a predetermined subroutine is called in a predetermined order in the third type processing without referring to either the storage contents of the first storage area or the storage contents of the second storage area. It is possible to assume processing to be executed.

  In the above embodiment, the main control CPU 100a is different from the storage area to be rewritten by the process in a part of the processing of rewriting either the storage content of the first storage area or the storage content of the second storage area. Although the storage contents of the storage area can be referred to, the present invention is not limited to this. For example, in all the processing of rewriting either the storage content of the first storage area or the storage content of the second storage area, the storage contents of the storage area different from the storage area to be rewritten by the processing can be referred to It is also good. According to this, it is not necessary to perform the same process as the process of rewriting the storage content of the predetermined storage area in the process of rewriting the storage area different from the predetermined storage area, and the processing of the slot machine 10 can be made more efficient overall. it can.

  In addition, in all the processing of rewriting either the storage content of the first storage area or the storage content of the second storage area, the storage contents of the storage area different from the storage area to be rewritten by the processing can not be referred to May be Further, while the processing of rewriting the storage content of the first storage area can be performed, the storage contents of the second storage area can be referred to, while the processing of rewriting the storage contents of the second storage area can not be referenced the storage content of the first storage area You may Further, in the process of rewriting the storage contents of the second storage area, the storage contents of the first storage area can be referred to, while in the process of rewriting the storage contents of the first storage area, the storage contents of the second storage area can not be referenced You may

  Specifically, the storage contents of the first storage area may be referred to in the second storage area check initialization process (the second type process). Further, in the second storage area power-on process (second type process), the storage contents of the first storage area may be referred to. Further, in the game progress processing (type 1 processing) regarding the progress of the game, the storage content of the second storage area may be referred to.

  The process performed by the main control CPU 100a may include a process of rewriting both the storage content of the first storage area and the storage content of the second storage area. That is, in the processing performed by the main control CPU 100a, the processing of not rewriting the storage content of the second storage area while rewriting the storage content of at least the first storage area, and rewriting the storage content of the second storage area A process that does not rewrite the storage content of the storage area may be included, and other processes may be further included.

  The main control CPU 100a saves the storage contents of the first storage area to the second storage area so that the storage contents of the first storage area can not be rewritten in the second storage area power recovery process. It may be saved in the storage area, or the stored contents may not be saved. Further, the storage content of the first storage area may be saved so that the storage content of the first storage area is not rewritten in all the processes of rewriting the storage content of the second storage area. According to this, it is possible to suppress that the storage content of the first storage area is unintentionally rewritten even though the processing does not rewrite the storage content of the first storage area. Further, the main control CPU 100a may save the storage content of the second storage area so that the storage content of the second storage area is not rewritten in the processing of rewriting the storage content of the first storage area.

  The processing procedure in various processes performed by the main control CPU 100a may be changed as appropriate. That is, in the processing performed by the main control CPU 100a, the processing of not rewriting the storage contents of the second storage area while rewriting the storage contents of the first storage area of the main control RAM 100c and rewriting the storage contents of the second storage area On the other hand, at least the process of not rewriting the storage content of the first storage area may be included.

  For example, in the process of step Se01 of the second storage area check initialization process executed in step Sc10 of the power on process, if it is determined that the storage content of the second storage area is not normal, the second storage area The second storage area check initialization process may be ended after setting the error flag to. In this case, when returning to the power-on process after completion of the second storage area check initialization process, it is determined whether the error flag is set or not, and if the error flag is set, the error is stopped If the error flag is not set, the process may proceed to the next process (step Sc11).

  Also, if a negative determination is made in the process of steps Sg03 to Sg05 of the second storage area power recovery process executed in step Sf04 of the power recovery process, an error flag is set in the second storage area, and The storage area power recovery process may be ended. In this case, when the process returns to the power supply recovery process after the end of the second storage area power supply recovery process, it is determined whether the error flag is set or not, and if the error flag is set, the error is stopped. If the error flag is not set, the process may proceed to the next process (step Sf05).

  Also, any one of the processing for restoring all the registers in the second storage area power restoration processing executed in step Sf04 of the power restoration processing (step Sg06) and the processing for restoring the stack pointer of the first storage area (step Sg07) One or both of the processes may be performed in the power recovery process. That is, in the second storage area power recovery process, when the affirmative determination is made in step Sg05, the second storage area power recovery process ends, and in the subsequent power recovery process, the process of recovering all registers and the first storage area A process of returning the stack pointer of may be executed.

The main control CPU 100a may be configured to be able to call and execute another type 2 process or type 1 process in the type 2 process.
The number of processes classified into the type 1 process and the type 2 process may be changed as appropriate. For example, the number of processes classified as the first type of process may be one, and the number of processes classified as the second type of process may be plural. Further, the number of processes classified as the first type of process may be plural, and the number of processes classified as the second type of process may be one. Further, the number of processes classified as the first type of process and the number of processes classified as the second type of process may be one. In addition, the number of processes classified into the first type of process and the number of processes classified into the second type of process may be plural, and in this case, the number of processes classified into the first type of process and The number of processes classified into two types of processes may be different.

  Interrupt processing may be employed as the first type processing or the second type processing. Further, interrupt processing may be adopted as the first type processing, and processing (a subroutine of interrupt processing) called by the interrupt processing may be adopted as the second type processing.

  The main control ROM 100b stores and holds the first storage area of the main control RAM 100c among the various processes performed by the main control CPU 100a in a specific storage area, while the second storage area In the process of rewriting, it may be configured to store and hold in a non-specific storage area different from the specific storage area. In other words, among the storage areas of the main control RAM 100c, the first storage area is a storage area to be rewritten by processing stored and held in a specific storage area of the main control ROM 100b, and the second storage area is It can be grasped as a storage area to be rewritten by processing stored and held in a non-specific storage area of the main control ROM 100b.

  -In addition, in the processing stored in a specific storage area of the main control ROM 100b, invoke and execute another process stored in a specific storage area or a process stored in a non-specific storage area It may be possible to Further, in the processing stored in the non-specific storage area of the main control ROM 100b, the processing stored in the specific storage area may not be called and executed. Further, in the process stored in the non-specific storage area of the main control ROM 100b, another process stored in the non-specific storage area may be able to be called and executed. You may

  The main control ROM 100b and the main control RAM 100c may be different memories, or may be different storage areas in the same memory. Similarly, the sub control ROM 200 b and the sub control RAM 200 c may be different memories, or may be different storage areas in the same memory.

  The backup power supply 300c of the power supply substrate 300 can supply power to the main control RAM 100c of the main substrate 100, but can not supply power to the sub control RAM 200c of the sub substrate 200. Good. That is, the sub control RAM 200 c may be configured to be unable to hold the stored contents when the power is shut off.

  The function of the sub substrate 200 may be divided into a plurality of substrates. For example, a display substrate for specializedly controlling the effect display device 15, an audio substrate for specializedly controlling the speaker 14, and a lamp substrate for specializedly controlling the decoration lamp 13 may be provided. You may further provide a general control board.

  The slot machine 10 may have a RAM clear switch for erasing (clearing) the stored contents of the main control RAM 100 c in addition to or instead of the setting device 26. In this case, the main control CPU 100a may execute the processing of steps Sc09 and Sc10 when the RAM clear switch is operated in the power on processing shown in FIG.

  The present invention may be embodied in a gaming machine using gaming media having a shape different from that of medals. For example, it may be embodied as a slot machine (so-called parrot) using a game ball (pachinko ball) as a game medium, or a pachinko game machine. When the pachinko gaming machine is embodied, for example, a RAM clear switch for erasing (clearing) the stored contents of the main control RAM 100 c may be provided as the operation unit capable of operation, instead of the setting device 26. At this time, the RAM clear switch may be disposed on the back side of the front door (machine), as with the setting device 26. Then, the main control CPU 100a may not rewrite the storage content of the first storage area while rewriting the storage content of the second storage area in the processing related to the operation state of the RAM clear switch. Since the RAM clear switch is an operation unit capable of rewriting the contents stored in the main control RAM 100c, it is likely to be a target of fraud. Therefore, the process related to the operation state of the RAM clear switch can be understood as an important process related to fraud. Further, the information rewritten in the processing relating to the operation state of the RAM clear switch can be grasped as the information relating to the fraud.

Hereinafter, technical ideas that can be grasped from the above embodiment and another example will be added.
